Patients with a deformity of the hindfoot present a particular challenge when performing total knee arthroplasty (TKA). The literature contains little information about the relationship between TKA and hindfoot alignment. This systematic review aimed to determine from both clinical and radiological studies whether TKA would alter a preoperative hindfoot deformity and whether the outcome of TKA is affected by the presence of a postoperative hindfoot deformity. A systematic literature search was performed in the databases PubMed, EMBASE, Cochrane Library, and Web of Science. Search terms consisted of “total knee arthroplasty/replacement” combined with “hindfoot/ankle alignment”. Inclusion criteria were all English language studies analyzing the association between TKA and the alignment of the hindfoot, including the clinical or radiological outcomes. Exclusion criteria consisted of TKA performed with a concomitant extra-articular osteotomy and case reports or expert opinions. An assessment of quality was conducted using the modified Methodological Index for Non-Randomized Studies (MINORS). The review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and registered in the PROSPERO database (CRD42019106980).Aims
Methods
Between 15% and 20% of patients remain dissatisfied following total knee arthroplasty (TKA). The SAIPH knee system (MatOrtho, Surrey, United Kingdom) is a medial ball and socket TKA that has been designed to replicate native knee kinematics in order to maximize the range of movement, stability, and function. This system is being progressively introduced in a stepwise fashion, with this study reporting the mid-term clinical and radiological outcomes. A retrospective review was undertaken of the first 100 consecutive patients with five-year follow-up following SAIPH TKA performed by the senior authors. The data that were collected included the demographics of the patients, clinical findings, the rate of intraoperative ligamentous release, patient-reported outcome measures (PROMS), radiological assessment, complications, and all-cause revision. Revision data were cross-checked with a national registry.Aims
Patients and Methods
Historically avoidance of avascular necrosis (AVN) has been the primary objective in the management of an acute unstable slipped upper femoral epiphysis (SUFE). When achieved through pinning in situ it was invariably associated with significant malunion. With increasing appreciation of the consequences of femoroacetabular impingement, modern techniques aim to correct deformity and avoid AVN. Exactly what constitutes an acute unstable SUFE is a source of debate but should represent 5–10% of all cases. This audit reviewed cases over the past 25 years treated in one region. Of 89 patients with 113 slips, 21 hips were recorded as unstable. During this period the management has evolved from closed reduction and stabilization through pinning in situ, to open reduction.
Magnetically controlled growing rod (MCGR) systems use non-invasive
spinal lengthening for the surgical treatment of early-onset scoliosis
(EOS). The primary aim of this study was to evaluate the performance
of these devices in the prevention of progression of the deformity.
A secondary aim was to record the rate of complications. An observational study of 31 consecutive children with EOS, of
whom 15 were male, who were treated between December 2011 and October
2017 was undertaken. Their mean age was 7.7 years (2 to 14). The
mean follow-up was 47 months (24 to 69). Distractions were completed
using the tailgating technique. The primary outcome measure was
correction of the radiographic deformity. Secondary outcomes were
growth, functional outcomes and complication rates.Aims
Patients and Methods
The aim of this study was to report the mid-term clinical outcome
of cemented unlinked J-alumina ceramic elbow (JACE) arthroplasties
when used in patients with rheumatoid arthritis (RA). We retrospectively reviewed 87 elbows, in 75 patients with RA,
which was replaced using a cemented JACE total elbow arthroplasty
(TEA) between August 2003 and December 2012, with a follow-up of
96%. There were 72 women and three men, with a mean age of 62 years
(35 to 79). The mean follow-up was nine years (2 to 14). The clinical condition
of each elbow before and after surgery was assessed using the Mayo
Elbow Performance Index (MEPI, 0 to 100 points). Radiographic loosening
was defined as a progressive radiolucent line of >1 mm that was
completely circumferential around the prosthesis.Aims
Patients and Methods
The aim of this study was to compare the functional and radiological
outcomes in patients with a displaced fracture of the hip who were
treated with a cemented or a cementless femoral stem. A four-year follow-up of a randomized controlled study included
141 patients who underwent surgery for a displaced femoral neck
fracture. Patients were randomized to receive either a cemented
(n = 67) or a cementless (n = 74) stem at hemiarthroplasty (HA;
n = 83) or total hip arthroplasty (THA; n = 58).Aims
Patients and Methods
It has been suggested that mobile-bearing total knee arthroplasty
(TKA) might lead to better outcomes by accommodating some femorotibial
rotational mismatch, thereby reducing contact stresses and polyethylene
wear. The aim of this study was to determine whether there is a
difference between fixed- and mobile-bearing versions of a contemporary
TKA with respect to durability, range of movement (ROM) and function,
ten years postoperatively. A total of 240 patients who were enrolled in this randomized
controlled trial (RCT) underwent a primary cemented TKA with one
of three tibial components (all-polyethylene fixed-bearing, modular
metal-backed fixed-bearing and mobile-bearing). Patients were reviewed
at a median follow-up of ten years (IQR 9.2 to 10.4).Aims
Patients and Methods
The classical longitudinal incision used for the direct anterior
approach (DAA) to the hip does not follow the tension lines of the
skin and can lead to impaired wound healing and poor cosmesis. The
purpose of this retrospective study was to determine the satisfaction
with the scar, and functional and radiographic outcomes comparing
the classic longitudinal incision with a modified skin crease ‘bikini’
when the DAA is used for total hip arthroplasty (THA). A total of 964 patients (51% female; 59% longitudinal, 41% ‘bikini’)
completed a follow-up questionnaire between two and four years postoperatively,
including the Oxford Hip Score (OHS), the University of North Carolina
‘4P’ scar scale (UNC4P) and two items for assessing the aesthetic
appearance of the scar and symptoms of numbness. The positioning
of the components, rates of heterotopic ossification (HO) and rates
of revision were assessed.Aims
Patients and Methods
We report the incidence of radiolucent lines (RLLs) using two
flanged acetabular components at total hip arthroplasty (THA) and
the effect of the Rim Cutter. We performed a retrospective review of 300 hips in 292 patients
who underwent primary cemented THA. A contemporary flanged acetabular
component was used with (group 1) and without (group 2) the use
of the Rim Cutter and the Rimfit acetabular component was used with
the Rim Cutter (group 3). RLLs and clinical outcomes were evaluated
immediately post-operatively and at five years post-operatively.Aims
Patients and Methods
To evaluate the outcomes of cemented total hip arthroplasty (THA)
following a fracture of the acetabulum, with evaluation of risk
factors and comparison with a patient group with no history of fracture. Between 1992 and 2016, 49 patients (33 male) with mean age of
57 years (25 to 87) underwent cemented THA at a mean of 6.5 years
(0.1 to 25) following acetabular fracture. A total of 38 had undergone
surgical fixation and 11 had been treated non-operatively; 13 patients
died at a mean of 10.2 years after THA (0.6 to 19). Patients were
assessed pre-operatively, at one year and at final follow-up (mean
9.1 years, 0.5 to 23) using the Oxford Hip Score (OHS). Implant
survivorship was assessed. An age and gender-matched cohort of THAs
performed for non-traumatic osteoarthritis (OA) or avascular necrosis
(AVN) (n = 98) were used to compare complications and patient-reported outcome
measures (PROMs).Aims
Patients and Methods
The purpose of this study was to compare the clinical and radiographic
outcomes of total ankle arthroplasty (TAA) in patients with pre-operatively
moderate and severe arthritic varus ankles to those achieved for
patients with neutral ankles. A total of 105 patients (105 ankles), matched for age, gender,
body mass index, and follow-up duration, were divided into three
groups by pre-operative coronal plane tibiotalar angle; neutral
(<
5°), moderate (5° to 15°) and severe (>
15°) varus deformity.
American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot
score, a visual analogue scale (VAS), and Short Form (SF)-36 score
were used to compare the clinical outcomes after a mean follow-up period
of 51 months (24 to 147).Aims
Patients and Methods
The aim of this prospective randomised controlled trial was to
compare non-operative and operative management for acute isolated
displaced fractures of the olecranon in patients aged ≥ 75 years. Patients were randomised to either non-operative management or
operative management with either tension-band wiring or fixation
with a plate. They were reviewed at six weeks, three and six months
and one year after the injury. The primary outcome measure was the
Disabilities of the Arm, Shoulder and Hand (DASH) score at one year.Aims

Introduction. A modern total knee replacement system was introduced in 2012 in order to improve the mechanics of total knee replacement (TKR). The purpose of this study was to assess the early clinical and radiographic outcomes of patients who have been treated with this modern TKR system at two years postoperatively. Methods. Patients who received this TKR system between June of 2012 and September of 2014 were included in this prospective registry-based follow-up study. Demographics, component, and surgical data were collected.
We report on the outcome of the Synergy cementless femoral stem
with a minimum follow-up of 15 years (15 to 17). A retrospective review was undertaken of a consecutive series
of 112 routine primary cementless total hip arthroplasties (THAs)
in 102 patients (112 hips). There were 60 female and 42 male patients
with a mean age of 61 years (18 to 82) at the time of surgery. A
total of 78 hips in the 69 patients remain Aims
Patients and Methods
Ankle arthroplasty is increasingly used to reduce pain and improve or maintain joint mobility in end-stage ankle arthritis. Both treatments show similar results with regard to functional outcome scores and sport related activities. However, the rates of complications and reoperations were higher after ankle replacement. Particularly for the first implant designs, with more promising results for newer designs. One of these newer designs is the Mobility Total Ankle System. Short term results in recent literature describe an improvement of functional outcomes; however complication rates vary widely, ranging from 9 to 37% and the 4-year survival rates ranging between 84 and 98 percent. Therefore, the aim of this study was to assess the clinical and radiographic short term results of the Mobility prosthesis. Between March 2008 and September 2013, 67 primary total ankle arthroplasties with the Mobility prosthesis were performed, in 64 patients, by one experienced foot and ankle surgeon. Complications, reoperations, failures and the survival rate were retrospectively examined. Patient reported outcomes were assessed with the use of the FFI score and visual analogue scale (VAS) for pain. Prosthesis alignment was measured on the first weightbearing radiographs of the ankle according to the procedure described by Rippstein et al.1 (Fig. 1).Background
Methods
The aims of this study were to describe the course of non-operatively
managed, bilateral Perthes’ disease, and to determine specific prognostic
factors for the radiographic and clinical outcome. We identified 40 children with a mean age of 5.9 years (1.8 to
13.5), who were managed non-operatively for bilateral Perthes’ disease
from our prospective, multicentre study of this condition, which
included all children in Norway who were diagnosed with Perthes’
disease in the five-year period between 1996 and 2000. All children
were followed up for five years. The hips were classified according to the Catterall classification.
A modified three-group Stulberg classification was used as an outcome
measure, with a spherical femoral head being defined as a good outcome,
an oval head as fair, and a flat femoral head as a poor outcome. Aims
